UNITED STATES PATENT OFFICE VLADIMIR V. MESSER, OF LOS ANGELES,CALIFORNIA, ASSIGNOR OF ONE-HALF TO A. F. GEORGE, OF LOS ANGELES,CALIFORNIA.

,ROAD-SURFACING MACHINE.

To all whom it may concern:

Be it known that I, VLADIMIR V. Masses, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Road-Surfacing Machine, ofwhich the following is a specification.

The object of this machine is to cut the surface of a road down, to trimthe. surface to a uniform level and remove ruts, ridges and inequalitiesin the surface.

Referring to the drawings: Figure 1 is a side elevation of the machine,with the cutting element in section. Fig. 2 is a front elevation withthe supporting wheels re moved. a

The machine comprises a frame consisting of two timbers 1, secured bytie-bolts 2, the rear end being supported by "a pair of wheels 3, andthe front end supfported by a pair of wheels 1, mounted on ront axle 5which is pivotally connected to the king bolt 6, the latter beingprovided with a shoulder 7 which rests on the front axle 5. The kingbolt 6 is guided by brackets 8 and 9. The bracket 9 is threaded andreceives a threaded portion 10 of the king bolt, the latter having ahand-wheel 11 for turning it. By revolving the king bolt 6, the screw 10may be moved up or down in threaded bracket 9 to adjust the end of theframe 1 the proper distance above the ground.

Mounted under the beams 1 is a rotary cutting element 12, comprising adrum 13 formed with pockets 14. Within the pockets 14. are star shapedcutters 15 which revolve on spindles 16. These cutters 15 are loose ontheir spindles and in the machine I have constructed, I employ aboutforty cutters on each spindle and rotate the drum 13 at about 1200 R. P.M. The drum 13 is keyed to a shaft 17 and carries a sprocket 18 which isconnected by a chain 19 with a sprocket 20 on the shaft 22 of an enginewhich is mounted on frame 1.

When the drum end of the machine is raised, the engine is started and bythen turning the hand-wheel 11, the drum 13 is brought down to thesurface ofthe road Specification of Letters Patent.

until the cutting stars 15 barely touch the ground. Then the machine ismoved along the road, either by horses or power and any projections onthe road which come under the drum are disintegrated by the cuttingstars 15, which revolve in a planetary manner, being carried bodily ina.circle by the drum, and also revolving on their own spindles bycontact with the surface which they are cutting. To protect the operatorfrom the flying loose dirt, the drum 13 is covered with a shield 23.

What I claim is:

1. A road surfacing machine comprising a frame, a cutter mounted on saidframe consisting of a rotatable member, spindles extendinglongitudinally of the rotatable member, star shaped cutters mounted onsaid spindles, means for rotating said rotatable member axially, meansfor moving said frame and rotatable member bodily along the roadway, andmeans for regulating the elevation of the rotatable member with respectto the roadway.

2. A road surfacing machine, comprising a frame, a cutter mounted onsaid frame, consisting of a rotatable member, spindles extendinglongitudinally of the rotatable member, star shaped cutters mounted onsaid spindles, means for driving said rotatable member, wheels supportinboth ends of said frame, and means for adJusting the wheels adjacent thecutters vertically with respect to the frame, to regulate the cuttingdepth of the cutters in the roadbed.

3. In a road dressing machine, a cutting element. comprising a drum withpockets and star sha ed cutters in said pockets, mounted to eely rotatewith respectv to the drum, and means for rotating the drum and starshaped cutters bodily, the star shaped cutters being caused to axiallyrotate by their cutting action in the roadway, and means traveling alongthe roadway for maintaining said drum at a definite elevation withrespect to the roadway.

4. A road surfacing machine, comprising a frame, a cutting elementmounted on the frame, supporting wheels near the cutting element, ashaft for the supporting wheels, In testimony whereof, I have hereunto athreaded hng bolt supported by said set my hand at Los Angeles,California this shaft, and a nut on the frame engaging the 16th day ofJuly 1912.
